yeah hope that the glue in it isnt poisonous or turns into an abrasive acid as a gas.. lol I'm sure you'll be fine heh you're not actually exposed to inhaling the duct tape as you use your bong are you? If you are the answer to this question could be kinda simple if you can taste bad things there is a high probability you're inhaling some noxious fumes... that said there are some chemicals agents that aren't readily detectable by our senses.. be careful it's not like you're using nerve gas to fix your bong


Peace and good wishes,
